INDIVIDUAL SIGNALING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 392,832, dated November 13, 1888.

Application filed July 19, 188B. Serial No. $280,402. (No model.)

To all whom t may conceive:

Be tknown that I, CHAnLEs N. TALBOT, of New York city, in the countyand State of Neu7 York, have invented a certain new and useful Improvement in Individual Signaling Apparatus, of which the following is a specification.

My invention relates to signaling systems of that character in which a number of signalreceiving devices are placed in the same circuit, and it is desired to operate or affect any Aone of such devices without affecting any of the others.

More especially my invention is intended to be used in connection with police-signaling systems, as a means whereby the attention of any policeman can be attracted from the police-station, so that he may know that the station desires to communicate with him and may proceed to his telephone-box and call up'the station.

The object of my invention is to produce an individualsignalingsystem which shallbemore effective and certain in its operation and less liable to error, and at the same time more simple in construction, than those heretofore employed.

To this end my invention consists in the various novel devices and combinations of devices employed by me in accomplishing the above-named object, as hereinafter set forth and claimed.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is aside elevation of the signalingtransmitter; Fig. 2, a top View of the same with the break-wheel in section; Fig. 3, an end view ofthe contact-making brush; Fig. 4, a side view of one of the signal-boxes with the door removed, Fig. 5, a vertical section of such box; Fig. G, a cross-section of the box, with a top view of the devices within it; Fig. 7, atop view of the arm which operates the signal-wheel, and Fig. S, a diagram of the circuits, showing the principal operating parts of the transmitter and receiver.

The transmitter at the central station is inclosed in a suitable box, A. Vithin this box is supported the transmitting breakwvheel, which consists of a body, B, ol' insulating ma terial, having a metal rim, C, provided with a number of teeth, a, whose number corresponds to the number of signal-boxes on the line. Upon one side of the insulating-body B is a metal ring, D, provided with a similar number of notches, b. The break-wheel is adapted to be revolved by clock-work, which may be placed in a box, E, and is connected with the shaft F of the break-Wheel. Upon the shaft F is a sleeve, G, which extends outside the box A, and has a handle, H, for turning it. On the inner end of the sleeve Gis secured an arm, I, which extends out beyond the rim of the break-Wheel, and has on its inner side a tooth, c, which enters the notches b. When the arm is turned by hand, it passes freely over the notches, but it is adapted to engage with said notches so as to turn with the wheel. Upon one side of the metal rim of the break-wheel a spring or brush, K, bears also, secured to the side of the box is an arm,

d, on the upper end of which is pivoted a small bent metal lever, e, whose inner end is in the path of movement of the arm I, and Whose outer end rests normally against a screw or pin, f.

Upon the surface of the break-wheel is placed a. stop-pin, g. Pivoted on a standard within the box is a three-armed lever, 7i 'i k. To the arm 7s of the lever is attached a spiral spring, Z, secured to the bottom of the box. rlhe arm f is adapted to engage the stop g for stopping the Wheel. M is a sliding bar havinga knob, N, outside the box for moving it, and carrying at its inner end a metal block, O,adapted to enter between two springs, m m. Pivoted upon this bar is a piece, n, having at one end a catch, o, and provided with a spring, p, which keeps it ina raised position. At its other end, the piece n has an inclined lower surface at q, adapted to slide over a pin, r, which rises from the bottom of the box. Two different positions of these parts are shown by the two sets of dotted lines. mitting-station I also provide a normally-open key, K', in a shunt around the break-wheel.

`Each of the signal-reeeiving mechanisms consists of a box, P, provided with a hinged door, Q. Within this box is a disk, R, having a notch, s, in its edge. In each ofthe dif- At the trans? IOO ferent signal-receivers the notch s is in a different situation on the rim of the disk, as is indicated in the diagram, Fig. 8. On the shaft of each disk R is a ratchet, S, with which engages a pawl, t, carried by an arm, T, journalcd on the shaft of the disk and having an armature, U, at one end. lIhis armature is placed in front of the poles of an electro-magnet, V. All the electro-magnets 'V are in series in circuit l. Each signal-box has also within it a magnet, XV, and all the magnets W are in series in a circuit, 2. Pivoted at a, be-

low the magnet V in each box, is a lever, X, from which hangs a pin, o, adapted to enter the notch s of the wheel. A t the long end of the lever is suspended, preferably, a shutter, Y, adapted to fall behind au opening` in the box, which opening may be vclosed by a pane of glass, Z, so that when the shutter drops behind the opening a visual signal will thus be given to any one observing the box from outside. Instead of this, however, an audible signal may be given, as is illustrated in the right-hand apparatus of Fig. 8, in which the arm Y is adapted to close a local circuit, iucluding a battery and a vibrating bell. It is evident that any desired number of signal-receiving devices may be included iu the circuits, cach having` its notch s at a different point. rIhe number of teeth ol' the ratchet S will correspond with the number of stations in circuit,and also with the number of notches a on the arm of the transmitting break-wheel. and the notches b on the ring D. Each disk R is also provided with a unisonstop, s', engaged by an arm, 1^','extending down at one side from the lever X.

Amain battery, A', maybe placed at the central station, which will supply current to the entire system.

Devices for resetting the parts of the signaling receiving apparatus after each one has been operated are attached to the door of each signal-box, so that the same will be operated by the movement of opening and closing the door. In the path of the shutter Y is a stop, w, secured to the side of the box, and immediately above it is a beveled projecting piece, x,

extending transversely from an arm, y, ex-

tending inwardly from the door in the path of the shutter Y, in whose lower end is a small slot or opening, z. Extending from the shaft of the wheel R is au arm, B, having a handle, C', -for moving it. In the bottom ofthe box is a sliding rod, a', whose end bears against the door, and which carries a block, b, and has coiled upon it a spiral spring, c', whose tension keeps the rod constantly against the door. Near the free edge of the door and about the middle ol' its height a curved arm, d', extends inwardly, said arm having at itslinner end au incline, c. Upon the upper side of this arm restsa rod, j", which has on .it aspiral spring, g', forcing it down, and also carries a pin, h', which extends over the short end of the lever X. Beneath the short end of this lever is a stop, t', extending from the side of the box.

The operation of these devices is as fol- Vlows: Normally the parts are all in the position shown in Fig. S, the circuit 2 being open at m m and closed at f, so that the magnets W are not encrgized,and the circuit l being open at L, so that magnets V are also not energized, and the lever-armi is against the pin (/,so that the break-wheel cannot turn. Supposing the operator at the station desires to signal box No. 5, he closes the circuit 2 by drawing forward the bar l\/I,so that the metal piece O enters between the springs m m,and by this same movement the catch o is brought against the leverarm h, and the lever-arm 't is thus withdrawn from the stop g,so that the break-wheel is free to move, and the clock-work having been previously wound up such wheel turns in the di` rection indicated by the arrow. As the baris pulled out,the inclined end q of the catch-piece a slides over the pin r, so that by the time the bar reaches the limit of its movement its inner end becomes depressed and the catch is disengaged from arm It, whereupon the spring Z will bring the arms hand t' back to their normal position, in which said arm t' is ready to engage again with the pin g when the wheel completes its revolution. Previous,however, to closing the circuit 2 and setting the breakwheel in motion, the operator moves the arm I down to a point corresponding with the number of the station he wishes to call-that is, wishing to call station No. 5, hemoves the arm down a space equal to iive teeth of the breakAwheel. rIhe closing of the circuit 2 causes all the magnets YV to lift the lever X away from the disks It,and they are heldthere until the turning of the break-wheel brings the arm I around to the pivoted contact c. As the break-wheel turns, of course the circuit 1 is alternately opened and closed and a succession of impulses is given by the magnets V to the ratchets S and disks R. The movement of the disks It thus corresponds precisely with that of the break-wheel, and

4when the arm I has reached the contact c the disk R at the station for which said arm I was set will have turned so far that its notch s is under the pin v ofthe lever, while in all the other stations the notches will be otherwise situated. As soon as the arm I reaches the contact e and moves it circuit 2 is opened atfand the magnets W are all de-energized, so that all the levers X fall against the disks It; but at station No. 5, the notch s be ing opposite the pin, said pin falls into said notch and the shutter Y drops behind the opening in the box, orsueh other signal is made as the apparatus is designed to produce. The break-wheel continues to turn until the pin g strikes the arm t' again, and of course the wheels R turn with it, and they are brought back to their normal or Zero position, except the wheel of station No. 5, which is held by the pin c in the notch s. The revolution of the break-wheel having been completed, the operator may again break the circuit 2 by pushing the bar M in, at which time the in- IOO ISO

clined end of the catch o passes under the lever h without withdrawing the arm i. The signal is thus in position at box No. 5 to attract the attention of the policeman or other person for whom it is intended, and the other signal-boxes are all in position to be operated in the same way without regard to the box already set.

It will be seen that the disks R provided with the notches s form adjustable stops for the lever controlling the signal, such stops being all differently situated relative to their respective levers, and that such stops are adj usted by a step-by-step movement due to the impulses communicated to the magnets V by the transmitting break-wheel.

When the policeman or other person observes the signal, he resets the same by rst opening the door of the boX, whereby the piece :r is withdrawn from the hole z in the shutter Y and such shutter isfree to rise. It is, however, at such a distance from the magnet W as not to be attracted by said magnet. The opening of thedoor also releases the rod a', so that the spring c' forces the block b into the path of the arm B'. At the same time the wedge d is pulled out so that its inclined end e comes under the rod f', and such rod is forced down by its spring g so that the pin h' strikes the short end of the lever X and raises the long end of the lever and shutter Y, so that the latter is held u p by pin h. Then by means of the handle C the disk R is turned until the arm B strikes the block b', at which time the notch s is brought to the proper position relative to the pins v, and the signal-box is ready for another operation as soon as the door is closed again, which pushes back the rods a', so as to move block b from in front of arm B', and also pushes up rod f so as to release .lever X.

It will be seen that there is no necessity for the policeman or other person to be informed as to the construction or operation of the apparatus, as he has simply to open the door, move the arm B until he can move it no farther, and then shut the door again. After this is done all the boxes will be in their original,`

position, with the pins o all resting on the rims of the disks It.

Since it sometimes arises in the operation of devices of this character that one or more of the ratchets S will drop a tooth during its revolution, or the signal-receivers may otherwise get out of unison, it is desirable to provide means whereby the transmitting operator may at any time and with certainty bring all the devices to unison, or automatic means may be provided for the same purpose. It is for this purpose that I provide the pin s and arm r at the signal-receivers and the key K at the transmitter.

It will be seen that when all the disks Rare at their normal or zero position, and when all the pins are resting on the rims of the disks, the arms r ought all to be against the pins s; but in order that the operator may be assured that this is the case and all the disks are in the right position, he may, by tapping the key K', communicate impulses to all the magnets V, and any disks R which are not .held from movement by the arms rwill be moved around until they are so stopped and held,whereby all the disks will be brought to the same position. When circuit is closed to the magnets lV in beginning the operation of signaling,the arms r are of course all raised away from the pins s', so all the disks R are free to move in unison with the transmitting breakwheel.
